RE: [Xen-users] Very Strange network problem

["Ian Tobin" <itobin@xxxxxxxxxxxxx>]

Hi,

Yes using bridged networking.  Strangely if i ping another host on the same 
network (pinging router doesn't work) from the dom0 console and leave it 
pinging the network stays up even after rebooting domUs.

As soon as i stop the ping and reboot the DomU the network stays off but the 
domU has network.  If I reboot the dom0 and reboot a domu say 5 times its fine, 
anymore and it starts to drop until i start the ping or reboot the dom0.

Its very odd, did you find a permanent fix? Obviously i can leave the ping 
running but its certainly not a solution.

Thanks

Ian

Are you using bridged networking by chance? I had seen something like
this on lenny where sometimes when I restarted or shutdown a domain
the host networking would drop out for about 15-30 seconds and I
always assumed it must be something related to the bridging.
